Description

Product Sheet

Classic series
Its objective, to maintain the philosophy of SUPRAVOX, full range driver units and high efficiency. We work still to widen the useful bandwidth for a highest efficiency possible, while unceasingly improving the definition, the quality and the linearity. Diameter 135 to 380 mm, the audiophile can satisfy its passion.

 

This loudspeaker of low register with high efficiency (98.5 dB) is intended for wiring for sound. Its engine made up of a ferrite of 220 mm makes it possible to obtain the field necessary to reach such a sensitivity.

These qualities enable him to be directly coupled with our 1 inch horn. Installed in a bassreflex, crossed to 1200 Hz, with a filtering with 18 dB/oct for the horn and 12 dB/oct for the 400, the response curve will be linear with ± 2 dB until the final frequency of the 1 inch driver.
